Deformable LED Lights

Nov 20, 2019
These bulbs died on me after about 21 months of occasional use; I replaced them in August, 2021.

Our garage has been lit by two 60-watt incandescent bulbs for as long as I've lived in this house (over a decade now). Until recently, that never really bothered me. Now that I'm into woodworking, however, and now that it gets dark early in the evening, the lack of light really started to strike a nerve. In thinking about potential solutions, I initially thought I'd install some LED strip lights in the ceiling, but doing this meant I would (a) have to mount the lights to the ceiling and (b) adjust the wiring for the existing sockets to accommodate for these new lights.

I found a much better solution in these deformable lights, which I picked up on Amazon. There are a million variations of these, from a million different Chinese companies, but these were some of the cheaper ones I found. The lights simply screw into the existing socket, and you can then point the three paddles in the direction you desire. I haven't used them a ton yet, but wow, the difference in illumination is night and day. I highly recommend them. Here's a picture of our garage taken tonight, with no flash:

I bought six of these for my garage (four of one brand; two of another; all via Amazon). After one month of intermittent use, one melted. So, I looked into LED circuit design. For these lights, they sometimes put a group of LED elements in series and then group multiple of those series strings in parallel. When they do that (the parallel part), unless there's a circuit to force the current to be the same in each parallel string, there's a serious risk of thermal runaway. [All of the discussions I've found suggest "current mirrors" to force the currents in the parallel circuits to match. The driver / power supply can only regulate the total current, so something else has to make sure that the current isn't getting hogged by one of the parallel strings.] I looked at my melted light. There are only two wires going to the surface-mount LED panel. The connections between LED elements on the panel are covered, but it appears that some of the strings are in parallel. There seem to be nothing but LEDs on the panel. So, there is no current mirror circuit. Amazon has some "better" garage lights - with the LED arrays mounted to aluminum panels instead of plastic. I haven't been able to find out if any of them have current mirrors (or if all of the LED elements are in series)... [I went back to the six 300W-equivalent CFLs that I had before.] The LED lights are nice and bright, but I'd rather not burn my garage down. I'll wait until they've been recalled and ones of a competent design are easy to find.
